I'm installing a new graphics card, and I can't quite figure out the best way to get power from the psu to the card. The psu is a seasonic x-750. If it matters, the motherboard is an Asus p8z68 v-pro. The gpu came with 2 adapter cables, each is a 6-pin to 2x 4-pin molex (well, 3 actual pins), but I have no molex plugs anywhere in the system. What cables/adapters would be best to use exactly? (I'll have to buy them, since I don't have any more cables around at the moment)

Since a picture is worth a thousand words, here are images of the power supply outputs, and the gpu input (standard 6-pin)











Thanks for your help.

And for further reference, these are the cables that should have came with the PSU:

Yeah, that's the main problem... I don't have any additional cables anywhere to be found. They should have come with the psu. And online, I can't seem to find a single 6-pin to 6-pin cable. They can't be that obscure?

Where could I find 2 of those?

Contact Seasonic and see if they'll sell you the cables or even give them to you if you never got them in the first place.

Thanks. Yup, that's what I need.

What are the differences between the same cable for different psu models? In this case, I would have figured a cable is a cable.

Does that mean it's necessary to get the specific seasonic cable, and not anything else that just looks the same?

Not only does it have to be Seasonic cables, it has to be for that specific model. Different cables from different manufacturers are made differently and won't even fit in the modular ports of other PSUs.

Long story short - you ONLY get cables from the same manufacturer and the cables have to be for that model.

Just now found this:

http://www.btosinte.com/Seasonic-12pin-to-two-62pin-PCIe-connectors-Modular-Cable-SS-122x62PCIe.htm

It looks like this should do the job, and I think it's the same item as in the image you posted. This should work in the 12-pin pci-e slot on the psu, and then have the 2x 6-pin plugs for the gpu. Good price too.

Just adding the end result, in case anyone else runs into this situation... Seasonic wrote back to me and directly gave me a link to order cables from their official distributor, which it turns out is the same company site I put a link to just above here. So I guess that is the best and only source.
